Sunshine streams through a vaulted skylight onto this magical penthouse duplex atop a charming prewar cooperative in the heart of Carnegie Hill. Greenery and flowers catch your eye from the wraparound terrace. Walnut-stained floors, mahogany French doors, 11-foot ceilings, shimmering Venetian plaster walls, bathrooms finished in handsome marbles, and a fantasy chef's kitchen of Gaggenau appliances are all part of this outstanding and pristine renovation. On the main level, off of the entry gallery is a square corner living room with a wood-burning fireplace and tall French doors that open onto a large wraparound landscaped terrace. Plants abound, nurtured by the sun and a full irrigation system. An outdoor wet-bar and dramatic lighting make entertaining memorable and easy. The cook's-delight kitchen, with its top-of-the-line appliances, allows you to close the mahogany pocket doors to cook in private, or open them to the light-filled dining room/family room, creating an uninterrupted entertaining space where guests can eat, relax, or wander onto the terrace. Tucked between the living room and dining area is a den or fourth bedroom with en-suite bath. A stunning black and white staircase leads to the upstairs bedroom wing, consisting of three full bedrooms and baths. Details such as leather handles on navy-lacquered closet doors, near-invisible built-in storage, a full oak dressing area, and marble bathroom, attest to the vision of the master-builder who created this dream home for himself. Located in the charming neighborhood of Carnegie Hill, this penthouse oasis represents sophisticated living at its best.
